研究东渡凹陷文东深层储层、构造特征及油气成残规模．通过用Jason储层预测技术，对文东沙四段进行储层预测；利用geoquest人权被作对沙四段顶底进行了构造精细解释；综合分析了油气成藏规律，认清了文东深层沙四段储层分布特征；发现有利构造圈闭3个。盐下深层以构造圈闭油气藏为主。文东深层存在早期凝析气和煤成气混合气藏，又具备良好的生、储、盖组合条件，其勘探资源潜力大，可以带动整个文南、文东盐下勘探。
To study the deep reservoirs and structural features of Wudong and the scale of hydrocarbon accumulation in Dongdu Depression. By using Jason reservoir prediction technology, reservoir prediction is carried out on the fourth member of Wandongsha; the geoquest human rights are used to make a detailed explanation on the top of Shahejie formation; the law of hydrocarbon accumulation is comprehensively analyzed, Segment reservoir distribution features; Found favorable structural traps 3. The sub-salt structure is dominated by trap oil and gas reservoirs. There is a deep gas condensate gas and coal gas mixture in the deep east of the Wendong region. In addition, it possesses a combination of raw, reservoir and cap conditions. Its potential for exploration has great potential and can drive the exploration of the entire Wennan and Wendong sub-salinity.
